Help! My custom mission apparently corrupted by DayZ mod...

[AlphaKappa 1]

I edited one of my custom missions while the DayZ mod was active, and now if I try to open it while DayZ is off, I get this:

"You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.dayz_equip"

Is there anything I can do to recover my mission? I'm pretty sure nothing on my map is DayZ-exclusive, but maybe there are certain vehicles/things that I should delete? I just have no idea which.

If you can help me, I would really appreciate it, as I've put dozens of hours into this custom campaign. Thanks in advance!

open and check your

mission.sqm

class Mission
{
addOns[]=
{
	// check here for anything unrelated to your mod but related to dayz (dayz_equip)
};
addOnsAuto[]=
{
	// same check here
};
(...)

otherwise check if you "editor placed" anything only available with dayz mod which should now be unavailable
